"It is a great mistake," said Sir Philip Cassim, looking doubtfully at the piece of paper lying on his desk; "then we were foolish boys, now we are--I trust sensible men. Certainly it is a great mistake." The piece of paper was yellow with age, a trifle grimy, and so worn with constant foldings, that it was wonderful the four quarters had not long since parted company, as had the four friends, each of whom carried a similar piece in his pocket-book. Often in his wanderings had Sir Philip pondered over that untidy boyish scribble setting forth the foolish promise, which he now, half regretfully, characterised as "a great mistake." "Bedford Grammar School, "_24th July, 1874._ "If we live and are in good health, we promise faithfully to meet at Philip's house, in Portman Square, London, on the twenty-fourth day of July, one thousand eight hundred and eighty-nine, at seven o'clock in the evening. "(Signed) "PHILIP WINTHORP CASSIM, JOHN DUVAL, PETER PAUL GRENCH, TIMOTHY TERENCE PATRICK FLETCHER." "That is quite fifteen years ago," said Cassim, smoothing the frail paper with tender fingers; "now it is the twenty-fourth day of July in the year eighty-nine. Six o'clock! I wonder if any of them will turn up. Jack is an engineer, building railways and bridges in China. Peter, as a respectable physician, doses invalids in Devonshire. Special Correspondent Tim, the stormy petrel of war, wires lies to London newspapers. I--I am a mere idler, given to wanderings among the tombs of dead civilisations. Peter may come. It means only a short railway journey to him; but Jack and Tim are probably thousands of miles away. Still, as I came from the Guinea Coast to meet them, they certainly ought not to miss the appointment. This is the day, the place, the hour, and I have prepared the fatted calf, of which they will partake--if they turn up. Pshaw! I am a fool to think they will come. They have, no doubt, quite forgotten this boyish freak. Perhaps it is best so. It is a great mistake to arrange a meeting fifteen years ahead. Father Time is too fond of strange surprises."
